steelseries: read settings from device

Browse Source 
Open an extra hidraw to read current onboard settings.

Initially DPI and static LED color can be read from the rival
310. Other data/devices can be added as the protocol is better
understood.

The protocol used to extract the data seems to be both device
and firmware version specific. To be able to switch on both
cases we now store the firmware information in the drv_data.
